2020 Census and Redistricting Thread: California

[I’m not Stu]

My map appears to knock out quite a few incumbents and leave open seats.

CA-01: ?
CA-02: Doug LaMalfa
CA-03: Tom McClintock
CA-04: ?
CA-05: Doris Matsui
CA-06: Mike Thompson

Yeah water continguity is a no-no unless there is a bridge.

[I’m not Stu]

Yeah water continguity is a no-no unless there is a bridge.

There are bridges (Richmond San Rafael and Carquinez).

Forgot about the them, thought they were further up in Napa.

The group of Democrats in my North Coast district are more liberal because it loses Marin County. Who might take my Emerald Coast district?

so I've drawn districts for the rest of the map. I figured better to do that first rather than see if/which further fixes might be done in LA.
for those who might worry: the successors to current CA-21 and CA-16 are still fundamentally the same in partisanship and are very similiar in Latino %. Though my CA-21 is more Bakersfield-heavy and my CA-20 (successor to old CA-16) is more Fresno-heavy.

Are those districts equally populated?

[Oryxslayer]

This map is similar in a lot of ways to what I got as my final map, but since I gave ethnicity a huge weight, there are a lot of slight differences. The West Fresno seat which makes CA21 (however it's drawn) more Bakersfield oriented is for instance is similar.

[President Punxsutawney Phil]

I did an edit of 2 Central Valley CDs designed to increase the Latino % in CA-20. It is now up to 65% Latino in 2018 total population.
No territory switched hands between any CDs other than CD-20 and CD-18.

When people do the pairing of Imperial and Riverside, everyone should try for something like this. Yes, the Hemet region gets traumatized like I hinted at earlier, however I suspect this is happens no matter what. The group is a 'jack of all trades, master of none' when it comes to the present CA41/42/36, and fits well in none of them. You grab San Jacinto, Valle Vista, And Banning, but not Beaumont. Such a seat is 59% hispanic and 46.5% Hispanic to 44.5% White VAP. Is this performing...well it's close but probably not. The seats main Hispanic base is Imperial after all, and turnout rates there are abysmal like the other rural Hispanic border counties to California's east. However, it is made safe Dem and does presently elect a Hispanic rep, so some might consider it good enough to be considered an New HVAP seat for the time being.

And yes, before people ask, everything is connected by roads despite the mountains. I74 connects Palm Springs and Valley Vista, and then Soboda road connects Valle Vista and San Jacinto. I need to state this since the two towns do not touch thanks to Hemet.

I only split Hemet slightly (in 3 districts; 36, 42, and 43), with most of it in the Escondido district (43). I did, however, place Beaumont with Banning in the Riverside-Imperial district.

So it seems the main difference between your Riverside-Imperial CD and mine is that mine relies more on natural boundaries?

Yep, this is a great example of one of those minor changes I referred to. I focused on getting as close to a new Hispanic seat as possible, you focused on staying on the far side of the San Jacinto range and follow the highway. Both are fine COIs.

re: changing seats in LA, one thing that worries me is that it'll risk erase a performing Latino CD I have on the map already. For instance the inclusion of East Los Angeles is important for CD-29 being as Latino as it is. Without East Los Angeles the CVAP plunges from 52% to 46%. And this is despite it being just 1/7 or so of the seat.
I also worry about the Asian seats. My CA-42 is tailor-made to be as Asian as possible and ought to be preserved as an Asian opportunity seat.

I have 3 plurality-Asian seats (CA-11: Ro Khanna, CA-30: Judy Chu, and CA-44: the Garden Grove-Huntington Beach seat). What's your CA-42?

Since Latino turnout is below-average the Asian hold on this seat would never be seriously threatened.

I redid some LA county seats. 7 of 16 seats in LA County changed in some form.
Turns out giving Pico Rivera to the 34th in return for most of Downey going to 30th worked out well.
The 29th is now wholely within LA city.
The 25th, 26th, and 28th all traded territory. The 26th gained all of the area around Beverly Hills, pushing the 28th west into parts of Van Nuys and North Hollywood, which in turn drove the 26th into areas just south of Northridge.
I also cleaned up the border between the 34th and the 35th to resemble a straight line, though the 34th will always have somewhat-incompact lines as long as the 42nd is the way it is.

The 30th remains the most Latino district on the map and in LA county.
Here are its stats:

It is inspired by that. Nunes gets drawn out. McCarthy is purple, light blue used to belong to Nunes, vermilion is Costa, and brown is Cox.
